[0002] Knives are a staple in every household kitchen. They are indispensable for daily cooking. However, due to wear and tear from daily use, knives will develop varying degrees of dullness. To address this, people typically sharpen the knives.

[0003] Sharpening knives is generally done using a whetstone or a sharpening tool. For example, Chinese patent CN204604133U discloses a sharpening tool, which is a relatively common sharpening tool. It has a sharpening groove on the sharpening base, and the cutting edge of the knife is inserted into the sharpening groove and rubbed back and forth to sharpen it.

[0004] However, these sharpeners are mostly fixed, with multiple slots concentrated on one end. The material and angle of the sharpening tool are fixed for each slot, making them impossible to adjust or switch. Users have diverse needs for sharpening their tools, such as fine grinding or general sharpening. Furthermore, different tools have different cutting edge angles, requiring different sharpening angles. Therefore, sharpeners with fixed materials and angles cannot meet various sharpening needs. While some sharpeners on the market offer adjustable sharpening modes, they generally use transmission mechanisms for adjustment, which suffer from complex structures, inaccurate switching, and a tendency to loosen, leading to inconvenience in use.

[0005] Therefore, it is necessary to provide a sharpening tool that allows for easy adjustment and switching between different sharpening methods to solve the above-mentioned technical problems. Summary of the Invention

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ,in, Figure 1 A schematic diagram of the external structure of the knife sharpener that allows switching sharpening modes via a push button, as provided in this utility model; Figure 2 This is an exploded view of the present invention; Figure 3 A schematic diagram of the grinding tool assembly structure; Figure 4 This is an exploded view of the bottom cover; Figure 5 This is a structural diagram of the bottom cover during assembly; Figure 6 This is a schematic diagram of the assembly of the grinding tool assembly and the left cover.

[0027] The knife sharpener that switches sharpening modes by pushing a button includes a housing 1, a lower cover 2 that engages with the bottom of the housing 1, and a sharpening assembly 4. The housing 1 is composed of a left housing 11 and a right housing 12, and forms an internal cavity for the sharpening assembly 4 to slide back and forth. A sharpening groove 13 is provided on the top of the housing 1.

[0028] The left shell 11 and the right shell 12 are made of high-strength, rust-proof, and corrosion-resistant materials such as metal or engineering plastics to prevent damage caused by kitchen fumes and extend their service life.

[0029] The left housing 11 and the right housing 12 are assembled and fixed by means of positioning pins and positioning holes, as well as threaded holes, threaded pins and screws.

[0030] The bottom of the lower cover 2 is provided with an anti-slip pad 3, which is in the form of a rubber coating or adhesive to prevent slippage when placed on a table.

[0031] It also includes a metal decorative piece 5, on which a groove corresponding to the grinding groove 13 is provided.

[0032] The sharpening assembly 4 has multiple sharpening positions on its top. The surface of the sharpening assembly 4 is provided with a button 411 that extends to the outside of the housing 1. Pushing the button 411 causes the sharpening assembly 4 to slide and be positioned within the housing 1, so that different sharpening positions correspond to the sharpening groove 13.

[0033] The sharpening assembly 4 includes a shell assembled from a left cover 41 and a right cover 42. The top of the shell has four grooves 44. Inside the shell, sharpening component mounting slots 43 are respectively provided on both sides of each groove 44. A set of sharpening components 45 are provided in the two sharpening component mounting slots 43 on both sides of the same groove 44.

[0034] Each groove 44, together with a set of grinding blades 45 inside it, constitutes a grinding position. By pushing the grinding blade assembly 4 to slide back and forth to different positions and positioning it, different grinding positions correspond to the grinding groove 13, so that different grinding blades 45 of different materials and angles can be selected for grinding.

[0035] In this embodiment, there are two grinding grooves 13, which are spaced apart, and four grinding positions are provided, numbered A, B, C and D from one end. Among them, grinding positions A and C are grinding blades 45 made of the same material, while grinding positions B and D are grinding blades 45 made of a different material. When the grinding assembly 4 is pushed to the front end, grinding positions A and C correspond to the grinding grooves 13. When the grinding assembly 4 is pushed to the rear end, grinding positions B and D correspond to the grinding grooves 13, which allows for quick switching between different grinding modes.

[0036] like Figure 2As shown, in order to ensure the stability of the movement of the grinding assembly 4 within the housing 1, guide protrusions 412 are provided laterally on the outer sides of the left cover 41 and the right cover 42, and guide grooves 201 for sliding of the guide protrusions 412 are provided on the inner sides of the left housing 11 and the right housing 12, respectively.

[0037] After the grinding assembly 4 is assembled, the left housing 11 and the right housing 12 are installed on both sides of the grinding assembly 4 and locked together to complete the assembly. At this time, the guide protrusions 412 on both sides are located in the two guide grooves 201 respectively, and the length of the guide groove 201 is greater than the length of the guide protrusions 412.

[0038] In this embodiment, when the guide ridge 412 slides to the front and rear ends of the guide groove 201, the grinding tool assembly 4 is at the front or rear end position.

[0039] The inner cavity of the outer shell is provided with a first elastic positioning member 47. The middle of the two guide protrusions 412 is provided with an elastic positioning member positioning hole 48 for the first elastic positioning member 47 to extend out. The inner walls of the two guide grooves 201 are each provided with two first positioning holes 202. When the grinding tool assembly 4 slides to different positions, the end of the first elastic positioning member 47 is engaged in different first positioning holes 202.

[0040] The first elastic positioning element 47 includes an installation cylinder. Movable telescopic clamps are provided at both ends of the inner cavity of the installation cylinder. The outer end of the telescopic clamp is a hemispherical surface and extends out of the installation cylinder. The inner cavity of the installation cylinder is provided with two elastic elements that respectively press against the telescopic clamps. When the telescopic clamp is squeezed, it will squeeze the elastic elements inward and retract into the installation cylinder. When the external force disappears, it will extend out again under the elastic force of the elastic elements.

[0041] The two ends of the mounting cylinder are respectively pressed against the inner wall of the positioning hole 48 of the elastic positioning element, and the telescopic clamp head extends and retracts along the positioning hole 48 of the elastic positioning element.

[0042] The two first positioning holes 202 on the guide groove 201 are spaced apart from each other, and the spacing is adapted to the sliding stroke of the grinding assembly 4. When the grinding assembly 4 slides to the front end, the telescopic head is engaged in the first positioning hole 202 at the front end. When the grinding assembly 4 is pushed backward, the telescopic head is squeezed back into the positioning hole 48 of the elastic positioning member. When the grinding assembly 4 slides to the rear end, the telescopic head is aligned with the first positioning hole 202 at the rear end. At this time, the external force squeezing the telescopic head disappears, and the telescopic head extends under the elastic force of the elastic member and engages in the first positioning hole 202 at the rear end, thereby realizing the positioning of the grinding assembly 4 at different positions.

[0043] A positioning seat 49 is provided in the lower part of the inner cavity of the outer shell. A second elastic positioning member 46 is provided in the positioning seat 49. The bottom end of the second elastic positioning member 46 extends to the bottom of the outer shell. A positioning block 21 is fixedly connected to the top of the lower cover 2. Two second positioning holes 22 are opened on the top of the positioning block 21. When the grinding tool assembly 4 slides to different positions, the bottom end of the second elastic positioning member 46 is engaged in different second positioning holes 22.

[0044] The principle of the second elastic positioning member 46 is the same as that of the first elastic positioning member 47. The difference is that only the lower end is provided with a telescopic locking head. The bottom of the grinding assembly 4 is provided with a hole or groove for the telescopic locking head to extend. The principle of the second elastic positioning member 46 and the second positioning hole 22 being engaged and positioned is the same as that of the first elastic positioning member 47 and the first positioning hole 202.

[0045] In another embodiment, in the AD grinding positions of the grinding assembly 4, the grinding blades 45 in grinding positions A and C are made of the same material but have different angles, the grinding blades 45 in grinding positions B and D are made of the same material but have different angles, and the grinding blades 45 in grinding positions A and B are made of different materials but have the same angle, and the grinding blades 45 in grinding positions C and D are made of different materials but have the same angle, thus forming four types of grinding materials and angles for selection.

[0046] Based on the above principles, more grinding positions can be set to achieve more changes in grinding materials, angles, etc. Correspondingly, the length of the grinding component 4, the size of the inner cavity of the housing 1, the number and position of the first positioning hole 202 and the second positioning hole 22 are also adjusted accordingly.

[0047] The outer side of the right cover 42 is provided with a mounting position 410 for mounting the button 411, and the right housing 12 is provided with a long groove 121 for the button 411 to extend and slide.

[0048] The position of the sharpening assembly 4 can be adjusted by directly pushing the button 411 from the outside to change the sharpening position for different sharpening operations.

[0049] It is also equipped with a handle 14, which is also divided into left and right halves and is integrally formed with the left shell 11 and the right shell 12 and assembled together. The handle 14 is equipped with a silicone pad for easy gripping.

[0050] The working principle of the knife sharpener that allows switching sharpening modes by pushing a button provided by this utility model is as follows:

[0051] By pushing button 411, the sharpening assembly 4 can be moved to change the position of each sharpening position on the sharpening assembly 4, so that the required sharpening position corresponds to the sharpening groove 13, and is positioned by the first elastic positioning member 47 and the second elastic positioning member 46, so as to select different sharpening positions such as material and angle for sharpening.

[0052] Compared with related technologies, the knife sharpener that allows switching sharpening modes by pushing a button provided by this utility model has the following advantages:

[0053] This utility model provides a push-button type sharpening device that switches between different sharpening modes. Multiple sharpening blades 45 are evenly distributed on a single sharpening assembly 4, with the distribution distance being the same. By engaging with the sharpening grooves in the housing 1, suitable coarse and fine sharpening materials or different sharpening angles can be selected. Simply pushing the button changes the position of the sharpening assembly 4, easily switching to the desired sharpening position. Unnecessary sharpening grooves are hidden, and a positioning structure is provided to prevent the sharpening assembly 4 from moving during use. The device has a simple structure, is easy to operate, and is highly practical.

[0054] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
